Call Python script from bash with argument

python linux bash shell debian

To execute a python script in a bash script you need to call the same command that you would within a terminal. For instance

> python python_script.py var1 var2

To access these variables within python you will need

import sysprint sys.argv[0] # prints python_script.pyprint sys.argv[1] # prints var1print sys.argv[2] # prints var2

Beside sys.argv, also take a look at the argparse module, which helps define options and arguments for scripts.

The argparse module makes it easy to write user-friendly command-line interfaces.
